2010 GT500 Engine Failure

So a club friend who has a 2010 GT500 Coupe with the FRPP 2.9l upgrade experienced engine failure this last Halloween giving a ride to a 10yo boy. The car is a two owner car, him being the second and a woman being the first. Car has 8,8xx miles on it, has always had 93+ octane gas used, oil was changed with Ford 5w-50 oil and has never been raced in any form. This boy was drooling over the car and asked for a ride, so he took him for one and after getting on the main road did a rolling punch from second gear - at about 4k rpm he says he heard a pop and miss so he clutched the car, saw some vapor and shut the ignition off, costing into a parking lot. I went with him to the dealer where it got towed. We talked to the service writer who took us to the SVT Tech in the shop. Due to a relatively small amount of water/oil on the ground the next day, he thought he popped a head gasket but the SVT tech said he'd never seen one loose a gasket or engine failure - he thought that the oil cooler on the driver side probably failed "or something stupid like that". So the next day the Tech gets the car on the rack and finds two small holes on both sides of the block??? The writer sent the below pic taken by the SVT Tech. The dealer seems not willing to pursue contacting SVT due to "age", not miles. They told him nothing can be rebuilt and that they suggest total engine replacement with a new engine for $22,000. They also said if the blower is damaged, it can't be rebuilt and will be another $7,000 or so. I think they just want to maximize the profit and get it done as quick as possible in the shop. He's like so sick and bummed he's not doing much but having it towed back to his house.

 

My question is does anyone have or know of a similar experience? Anybody have a contact we could pursue at SVT? The SVT Tech said he has never seen one of these engines blow while working for Ford. He was very surprised.

It's possible that this is a fluke of an issue on a block with a bad casting that slipped through QC. Other than that, the lack of use or even an unshared issue left by the prior owner. The only way to true understand what went wrong to autopsy the engine.

 

Years ago I had a 3.0l Ranger with less than 15k-20k miles suddenly and unexplainabley break a valve spring while on my morning commute to the office. It was a fluke. A random and extremely unlikely failure. However, it concerned me enough that I traded that Ranger for and F150 less than a year after it was repaired as I was concerned that lighting would strike again because it was such a fluke issue. While I know this isn't true in past 15-20 years I was concerned about the old adage that you never purchase a car built on a Friday, and I wonder if that Ranger was built on a Friday.

 

Depending on your buddy's situation, going to a specialist to rebuild is an ideal option, but so is selling the car as is and looking for another GT500. Understandably not everyone has the desire to go through an engine rebuild/replacement when all they are after is a car they can cruise and enjoy.

 

Wish him luck on any choice he makes, there isn't a wrong option.

I've seen stuff like this happen on stock engines, so with a Whipple sitting at the top of the engine it's not THAT uncommon. Just depends on how much boost he was running and what tune he had.

 

I'm guessing an FRPP tune but I don't know.

 

If the heads aren't damaged your friend can just get a built shortblock from FRPP for about $3,500

 

He'd have to pay to pull the motor and swap the heads, accessories etc. or if he's mechanically inclined he could pull the engine himself.

 

I would expect around 3k to pull it and swap it.

 

So $6500 roughly for a new built FRPP short block, but it all depends on what your buddy wants.

Thanks guys, Ford said since he was not the original owner (2nd) that and the fact it's the years and not the miles (8,800), he gets the middle finger salute. He's owned the car for ~18 months so it's unlikely the previous owner hurt it. He's never raced it on the strip or street but have done spirited driving - nothing that would cause rods to give way. MMR has a 1,000 HP short block for $3,500 so we are going to pull heads and see if they are damaged. Sucks ...

 

Ford SVU mechanic verified the tune was correct for this blower kit at 16 psi.

Could have been over-revved by the previous owner. I could picture bouncing off the rev limiter during a burnout, or over-revving while accelerating in lower gears. Usually when a rod goes, it's been "stretched" a hair, due to the over-revving, and won't fail immediately. Now with the rod being out of round, the accumulated miles after the over rev, add up, and one day out of the blue, it can let go. Rods are strong, and to break one on just power alone, is tough to do. Over rev it, and all bets are off!

He ordered the MMR 1000HP 5.4 short block with billet pump, Manley H beam rods, ARP head studs, Extreme duty Fel Pro gaskets. About to go in. I've read these engine REALLY don't like bouncing off the limiter due to rod bolts and powdered metal gears in the oil pump.

That is a good short block with some serious goodies inside, for a reasonable price.

They also rate that as 1000RWHP capable too, which offers a lot of overhead.

If you have to fix something, it is always nice to fix it better than it was.

If he needs to get a new blower, he can pickup a VMP GEN2 with goodies for less than $4K.

I am running one now and it makes some serious torque and horspower, my 1/4 mile mph is now beyond 127 with ease in full street trim/weight.

Update, after getting the MMR short block installed and getting package tune to self learn and mild detonation at load to stop,  The computer crapped out.  I got a sneaky suspicion a computer glitch caused a misfire near BDC and took out #5 piston/rod.  Ford put a new one in for free due to emissions but it took 2 months to get a new computer made up = Ford had NONE in the country.
